Each year I continue to see teachers frustrated when they get their middle of year testing results back for their class because Geometry is often one of the lowest strands. Over the years I have puzzled about why this is but have realized that most textbooks (ours included) waits to teach Geometry until the last couple of units. So many teachers who rely heavily on the textbook do not teach Geometry until right before the state test. Often this means students get told about geometry instead of getting the opportunity to experience it through hands on application and discussion.
So why do we wait until the last minute to teach geometry?
I would like to propose that we teach geometry throughout the year by incorporating geometric ideas into instruction of other standards. I would argue that too often we teach skills in isolation and don’t connect the mathematical ideas.
In Kindergarten, instead of giving students random objects, have them count shapes such as triangles, squares, rectangles, circles and as they develop the idea of cardinality have them confirm their count by labeling the objects. For instance, if they count nine triangles, they would say “there are 9 triangles.”
Provide multiple types of triangles so that they can develop the idea that triangles come in all sizes and orientations and that counting does not have to be an object of a particular size or congruency.
We were just discussing this in Kindergarten and 1st grade team meetings this week. We want to revise our curriculum map to incorporate geometry and data throughout the year with the other strands, especially at the beginning of the year. Like you mentioned when you’re learning numbers, why not learn them by working with shapes or recording data.

Awesome! I’d love to hear what you come up with:) Let me know if you want help thinking through it.
